I was wondering how exactly do we calculate what our Reservoir has in it?
I mean I have a fertilizer kit which tells me what each bottle has in it as far as NPK. But the actual Ingredients are more or less unknown.
Calculators I’ve seen want ppm values and each component but I have no idea.
Is there a way to calculate just NPK numbers based on how many mL I put into a gallon?
I use 25-50% of the minimum value they indicate per gallon which also makes it more complex.
Anyone encounter and figure out this problem?
One other thing,
I’ve also read the goals for NPK during stages were:
early veg state 4-2-3 and med veg state 10-5-7
But I didn’t see what they are for Flowering from the grower I saw that recommendation from. Any truth to these guidelines?
Thanks
